TDA7388 Datasheet – Car Radio Amplifier

Part number : TDA7388

Function : Quad Bridge Car Radio Amplifier

Package : Flexiwatt25, HZIP-25 Pin Type

Manufacturer : STMicroelectronics,  Unisonic Technologies



The TDA7388 is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed for high end car radio applications. Based on a fully complementary PNP/NPN configuration, the TDA7388 allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.
